ELEVATING BAGGAGE TRUCK.

Application filed. April 17,

To all whom it may concern:

Be it known that I, JULIAN L. CRAoRAFT, a citizen of the United States, residing at Georgetown, in the county of Scott and State of Kentucky, have invented certain new and useful Improvements in Elevating Baggage Trucks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to trucks such as are used for conveying baggage or other objects from one place to another, and

. 16 aims to provide a novel and improved truck having means for elevating the load for the convenient loading and unloading of the truck.

Another object of the invention is the provision of such a truck having novel and improved means between the wheel-mounted frame and the top or deck for raising said deck in a simple, practical and eflicient manner to elevate the load.

With the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of the truck with the deck or platform in lowered position.

Fig. 2 is a horizontal section on the line 2-2 of Fig. 1.

Fig. 3 is a side elevation showing the deck raised.

In carrying out the invention, there is provided a suitable frame 7 mounted on the wheels 8, and having the transverse end bolsters 9. The top or deck 10 has transverse bolsters 11 at the under side thereof to seat on the holsters 9 when the deck is in lowered position, as 'seen in Fig. 1.

The elevating device includes a pair of levers or arms 12 pivotally or hingedly conneeted to bearings 13 secured to each bolster 9 at the inner side thereof. The levers at the opposite ends project toward one another, and said levers are provided at their free ends with rollers 14 to bear against the 1922. senlu No. 553,797.

lower surface of the deck or top 10, whereby the levers in being swung upwardly, will raise the deck, such rollers reducing the friction between the levers and deck and providing for a free and easy motion.

In order to swing the levers 12 for raising and lowering the deck, a longitudinal shaft 15 is journaled through the bolsters 11 and through cleats or bearings 16 secured to the lower surface of the deck between B the bolsters 11, and collars 17 are secured to the shaft at the opposite sides of said bolsters 11 and bearings 16, for retaining the shaft against longitudinal movement. The shaft is thus carried by the deck under- 7 math same, and is formed with the reverse screw-threads 18 between the bolsters 11 and adjacent bearings 16. A transverse bar or cross head 19 is disposed between each pair of levers 12 and has a nut portion 20 between its ends threadedly engaging on the cor responding screw 18, whereby the rotation of the shaft 15 will move the cross heads 19 in opposite directions in view of the fact that the screws are reversed. The terminals 0. of the cross heads 19 have portions 21 working within longitudinal slot 22 in the levers 12, providing slidable and pivotal connections between the cross heads and levers.

The shaft 15 is rotated by any suitable means, such as a hand crank 23 attached to one end thereof.

The truck can be conveniently loaded with the deck 10 in lowered position, and in order to conveniently unload the truck at a-higher level, the deck is raised. In order to raise the deck, the shaft 15 is rotated in the proper direction to move the cross heads 19 toward the bolsters 11, whereby the portions 21 of the heads in working in the slots 22 will swing the levers 12 upwardly, and the rollers 14: in travelling under the deck, will raise said deck. The levers 12 can be brought to a vertical position, as

seen in Fig. 3, to support the deck in its highest position, with the cross heads 19 adjacent to" or bearing against the bolsters 11. By reversing the rotation of the shaft 15, the cross heads are moved away from the bolsters 11, thereby lowering the deck until it seats on the frame 7. 7

Having thus described the invention, what is claimed as new is A truck comprising a wheel-mounted frame, a deck above said frame, two 10 pairs of levers hingedly connected to the rectly on said levers when the levers are frame and having portions contacting with swung upwardly.
